Abstract
Terra Nova, 25, 65–71, 2013 Abstract We present results from experimental gravity and turbidity currents to show that at high latitudes, the Coriolis effect strongly influences the internal flow structure in submarine channel systems. At high latitudes, Coriolis forces deflect the downstream velocity core, and consequently areas of deposition and erosion, to one side of the channel system. Over time, this supports the evolution of low‐sinuosity submarine channels. These findings help explain the recently found relation that channels at low latitudes often show strongly sinuous planform geometries, whereas channels at high latitudes tend to be much less sinuous. On the basis of our observations and an existing conceptual model for channel evolution, we propose a process model for sedimentation regimes in turbidity currents, which is applicable to all latitudinal settings.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
